How to make roses bloom early

Rose is a kind of flower sequence sensitive to light and temperature. it often loses its leaves and hibernates because of low temperature in northern China. However, because it has the special physiological function of accumulating temperature and promoting growth, it can accumulate the sometimes high and sometimes low temperature under certain temperature and light conditions to meet the needs of its growth and development, so appropriate measures can be taken to make it bloom in advance at the beginning of the year.

1. Selecting cold-resistant ink red and pink rose varieties, this rose has the characteristics of thick branches, luxuriant branches and fast growth of new shoots, the first leaves are purplish red, the compound leaves are mostly composed of 3-5 leaflets, and the leaves are small and thick. Branchlets are precocious and can give birth to buds when they have 3 or 5 compound leaves. Hardwood cuttings in spring can start flowering at the beginning of summer. Xie Hua branch cuttings in summer can begin to bloom in early autumn.

Second, forcing dormancy with leaves at the end of autumn in order to make ink red rose blossom early at the beginning of the year, the baking basin must be stopped at the end of autumn, so that it can have a long period of dormancy with leaves, so that nutrients can be returned to the root and strengthen the growth momentum after recovery.

Third, renew the branch sequence before the middle of winter, move the dark red rose that forces the dormancy of the leaves to the half shade below the balcony railing, cut off 3 trees, and cut a large number of dense branches, rehydration and topdressing at the same time, promote the sprouting and spreading leaves, make the old leaves take off and the new shoots elongate, so as to achieve the purpose of renewing the branch order and leaf curtain.

Fourth, protect leaves and promote buds in cold winter. in cold winter, move the flowerpot under the indoor southward window and keep room temperature for 5: 10 ℃ to prevent tender branches and leaves from being damaged by cold. At noon on a sunny day with high temperature, the sun can be placed on the balcony to increase the accumulated temperature needed for growth and development, and properly dry the baking pot while maintaining a certain humidity of the leaf curtain, so as to promote the bud differentiation at the top of the shoot.

In May, the strong leaves began to blossom to early spring and February, a deep ploughing was carried out, and the mixed chemical fertilizer based on phosphorus and potassium fertilizer was re-applied. Both sunny and cloudy days are placed on the balcony to prolong the lighting time. In winter below 3 ℃, it is necessary to move indoors under the window to keep warm, and spray water to moisturize the leaves from time to time, so that the leaves are red and green, from small to large, enhance photosynthetic function, form a few strong buds and start flowering.

Sixth, the flowers bloom before and after the Qingming Festival before and after the Spring Equinox. If there is no spring cold, they can be moved to the flower rack of the southward balcony for normal daily management, so as to promote the new leaves to change from red to green quickly and differentiate more robust buds as soon as possible. each flower branch retains a top bud. Spray 0.1% potassium dihydrogen phosphate and 0.2% boric acid mixture every 3 days in the bud stage for 2 times to strengthen leaves and buds and promote them to bloom before and after the Qingming Festival.
